The TPD4S1394DQLR is a four-channel ESD protection array from Texas Instruments, purpose-built for FireWire (IEEE 1394) ports. It uses Mixed Technology — a combination of TVS diodes and a crowbar circuit — to clamp transients at 2.45V, well below the damage threshold of the 1394 transceiver it protects.
Surface-mount only — no through-hole variant.
It uses Mixed Technology — a combination of TVS diodes and a crowbar circuit — to clamp ESD and surge transients at 2.45V. This keeps the voltage seen by the FireWire transceiver within its safe operating area during an ESD event. Four independent protection channels cover the signal lines of a single 1394 port.
The TPD4S1394DQLR is the Tape & Reel packaged variant of the base TPD4S1394 device. The electrical specifications — Mixed Technology, 2.45V clamping, four circuits, FireWire application — are identical. The DQLR suffix indicates the 8-X2SON package in Tape & Reel format; the base part number TPD4S1394 may also be available in other packaging options.
